hazarding a guess: adns.net looks wonky :( a.gtld-servers.net says: ( for and NS set query) ;; ADDITIONAL SECTION: ns1.adns.net. 172800 IN A 199.5.157.2 ns2.adns.net. 172800 IN A 199.5.157.3 czones1.american-webmasters.net. 172800 IN A 199.5.157.129 czones2.american-webmasters.net. 172800 IN A 199.5.156.253 kovu.adns.net. 172800 IN A 199.5.157.52 nebula.adns.net. 172800 IN A 3.134.129.157 and the first in that list that replies fo dns requests: 3.134.129.157 / nebula.adns.net. says: NS1.ADNS.NET. 3600 IN A 199.5.157.2 NS2.ADNS.NET. 3600 IN A 199.5.157.3 KOVU.ADNS.NET. 3600 IN A 199.5.157.52 NEBULA.ADNS.NET. 3600 IN A 3.134.129.157 QUASAR.ADNS.NET. 3600 IN A 198.180.140.2 NS1.ADNS.NET. 3600 IN AAAA 2602:f813::1:c705:9d02 NS2.ADNS.NET. 3600 IN AAAA 2602:f813::1:c705:9d03 KOVU.ADNS.NET. 3600 IN AAAA 2602:f813::1:c705:9d34 NEBULA.ADNS.NET. 3600 IN AAAA 2600:1f16:ec1:a1b4:767d:df35:b9b9:2581 QUASAR.ADNS.NET. 3600 IN AAAA 2602:f813::1:c6b4:8c02 NONE of the 199.5/16 ips reply at all for dns.. that seems bad :( or at least 'sub optimal'. In that second answer the only not-aws IPv4 address that replies is: 198.180.140.2 -chris (yes this is the 'additional section' content from dig NS @<thing> domain) _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/JFVO7ZDLJVNVRX473S6ZR23HYZAJ3I4V/
